Ammino-ferric Chloride.—Anhydrous, ferric chloride forms hexammino-ferric chloride, [Fe(NH3)s]Cl3, en exposure to ammonia gas. The compound loses" one molecule of ammonia on keeping fix a dry atmosphere at ordinary temperature, giving the pentammine, [Fe(NH3)6]Cl3, and on heating to 100° C. the tetrammino-derivative, [Fe(NH3)4]Cl3, is formed. Further heating causes complete dissociation with formation of ammonium chloride. The addition compounds are not deliquescent and are insoluble in water, but lose ammonia and chlorine when repeatedly washed with water.3... [Pg.127]

Hexammino-vanadium Trichloride, [V(NH3)6]C13.—The similarity between the trichlorides of iron and vanadium is further shown in their behaviour towards ammonia. At ordinary temperatures ammonia reacts with vanadium trichloride to produce vanadium nitride, VN, and ammonium chloride, but if liquid ammonia is poured over vanadium trichloride, a quantitative yield of a reddish-brown salt, [V(NH3)6]C13, is obtained, which recalls the hexammines of cobalt and chromium. The ammonia molecules are not, however, very firmly held, and the compound is, therefore, more comparable with the corresponding hexammine of ferric chloride, [Fe(NH3)6]Cl3. [Pg.42]

In order to avoid an accumulation of iron compounds (max 50 mg. Fe per litre) a oertain portion of the circulating liquid is led into spacious precipitating tanks where it is neutralized by gaseous ammonia. The precipitated ferric hydroxide is allowed to settle and the clear solution is siphoned and boiled down. The separated crystals of pure ammonium sulphate are centrifuged and recycled into the electrolytic process. [Pg.412]

A solution of 150 g. of ferrous sulfate in hot water is added rapidly to a solution of 10 g. (0.064 mole) of 5-nitrouracil (p, 238) and 150 ml. of concentrated aqueous ammonia solution in 600 ml. of hot water. The resulting mixture is boiled for 30 minutes. The precipitated ferric hydroxide is removed by filtration, and the filtrate is concentrated. When the filtrate is cooled the amino compound precipitates, and it is purified by solution in a minimum volume of dilute hydrochloric acid followed by reprecipitation with dilute ammonium hydroxide solution. There is obtained 5.5 g. of 5-aminouracil corresponding to a yield of 68%. [Pg.28]
